Abstract

The ultra-wideband ground penetrating radars (GPRs) are successful in sensing not only conductors but also dielectric objects. For that reason, GPRs are used in many applications to detect and identify objects, which are hidden behind obstacles such as walls or buried under ground. In such problems, the early reflections from the wall or ground surfaces are very strong. These strong electromagnetic wave components must be removed during the "preprocessing" phase by suitable and effective methods as they lead to detection/identification errors by masking the relatively weak signals reflected/scattered from the actual targets.
